use this if you get called ugly

other scenarios: bully: stupid nerd
you: nerds are the ones who make things, new technology, so don't go begging on my knees for forgiveness later in life
another one:
bully: hey midget, you look like a baby, you baby
you: if I'm a baby, you're a pouty toddler

more:
bully: you are disgusting
you: and so is your attitude

even more:
bully: calls you gay
you: is this a proposal?
(this only will work if you're the same gender)

still more:
bully: stfu no one cares
you: I've had more people agree with me than you

bully: go die in a ditch, stupid kid
you: ladies first.
(if you don't get it you're basically calling them wimpy, this is a bit of an offensive joke, don't come after me)

even more, this one is fire:
bully: your smarts are fictional
you: and so are your friends

EEEEEK! DATS GOTTA HURT!!!
